Several of these genes have been found to be associated with myocarditis (some with confirmed viral etiologies) in adults and children that may predispose them to developing cardiomyopathy after viral infection including DYS (dystrophin), BAG3 (BAG family molecule chaperone regulator), DSP (desmoplakin), PKP2 (plakophilin-2), RYR2 (ryanodine recepter-2), SCN5A (sodium ion channel) or TNNI3 (cardiac troponin I) [64,65,66]. This evidence concerns the gene PKP2 and viral infectious disease.
